A new head-mounted display (HMD) offers surgeons enhanced 3D visualization for improved safety and efficiency in microsurgical and endoscopic procedures. This stereoscopic HMD system is comfortable, reliable, and enhances operative field access and dexterity.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Previous evaluations of video technologies for electronic imaging in microneurosurgery and endoscopic procedures.
  • Development of stereoscopic camera systems for surgical visualization and recording.
  • Need for advanced visualization tools to support surgical teams.

Purpose of the Study:

  • To describe a novel prototype head-mounted display (HMD) for surgical use.
  • To evaluate the HMD's capabilities, including stereoscopic visualization, picture-in-picture, voice control, and stereoscopic recording.
  • To assess the HMD's impact on surgical procedures and team performance.

Main Methods:

  • Design of a stereoscopic HMD with 640 x 480 pixel resolution and 24-bit image display.

  • The HMD weighs 900 g and interfaces with common video display formats.
  • Prospective multicenter trial evaluating the HMD in open microsurgical and endoscopic procedures.

    • Main Results:

    • No equipment failures or complications reported in initial trials.
    • Users reported significant benefits in visualization and accepted the equipment well.
    • The HMD is comfortable, reliable, and provides excellent field of view and 3D perception.

    Conclusions:

    • Stereoscopic HMD use may improve efficiency and safety in endoscopic and open microsurgical procedures.
    • Enhanced positioning, dexterity, and operative field accessibility confirmed.
    • Potential applications include surgical training, multimodal information display, and operative rehearsals.
